an expression used by people under the influence of marijuana when they feel that someone has completely ruined their good mood, or "killed their high"

here is an example
*people hotboxing in a car*

Andrew: man, this is some good shit!

Eric: yea, it is- HOLD ON! DUDE! I JUST SAW A COP OVER THERE! HIDE THE BUD! HIDE THE BONG!

John: *looks for the "cop"*; what the fuck, thats not a cop, thats just an old lady in a white lincoln

Andrew: Eric! wtf!! your killing my high! stop being so paranoid.
